For children 5 years and older (school-aged kids and teens), 3‑Hexenol — a scent ingredient — is generally low risk when used in normal, diluted skin products. Major safety reviews say it is unlikely to cause cancer, allergy, or reproductive harm, though a few studies show very small concerns at high doses or with direct eye contact.
Use products that list this ingredient only on normal skin and in finished products (not raw fragrance oil). Do a small skin patch test first: put a drop on the inside of the forearm and wait 24 hours. Keep products away from the eyes and broken skin. If a product smells very strong or is a concentrated fragrance, avoid using it on children.
Watch for skin redness, rash, persistent eye sting, or breathing changes and stop use if these happen. Limited eye irritation was reported by the European Chemicals Agency, and a government toxicology review (National Toxicology Program) noted weak hormone-related findings in some studies — these were small effects seen in research, not in typical product use. Animal studies at very high doses showed kidney effects; those high doses are not the same as normal product exposure. If you see any reaction, rinse the area and contact your pediatrician.
